Shortcut Formulas

Following are some Quantitative Aptitude Formulas which can be used as a CAT Quant Formula Cheat Sheet for the preparation and exam point of view:

1. If the distance covered in each stage of the journey is the same, but speeds are different, then the average speed is the harmonic mean of the different speeds.

Ex: If distance between point A to B and B to C are same and are covered with the speed of s1 and s2 respectively. Then-

Average Speed=2S1S2S1+S2

2. If the time taken in each stage of journey is same, but speeds are different then, the average speed is the average of the different speeds.

Ex: If time taken between points A to B and B to C is same and these distances are covered with the speed of s1 and s2 respectively. Then-

Average Speed=S1+S22

3. If two people start running on a circular track of length D km in the same direction from the same point with speeds a & b kmph, then-

(i) Time taken in first meeting=D|a−b| hr

(ii) Time taken to meet again at the starting point=LCM(Da,Db)

(iii) Number of distinct meeting points=|x−y|

{x & y are the simplified ratio of speeds, Ex: If speeds a & b are 12 kmph & 9 kmph

respectively, then- x: y = 12: 8 = 3: 2; So, x = 3 & y =2}

4. If two people start running on a circular track of length D km in the opposite direction from the same point with speeds a & b kmph, then-

(i) Time taken in first meeting = D|a+b| hr.

(ii) Time taken to meet again at the starting point = LCM (Da ,Db) hr.

(iii) No. of Distinct meeting Points = |x + y|

{x & y are the simplified ratio of speeds}

5. If a person P starts from A and heads towards B and another person Q starts from B and heads towards A and they meet after a time 't' then, t=(x.y)

[where x = time taken (after meeting) by P to reach B and y = time taken (after meeting) by Q to reach A]

6. If the speed of the boat downstream is u kmph and the speed of the boat upstream is v kmph, then-

Speed of the boat in still water=u+v2 kmph

24/3<a<24/2

8<a<12

So, all possible values are 9,10,11 cm.

4. Let a,b,c are sides of a triangle, and a is the greatest side.

If a2<b2+c2

Then triangle is an acute angled triangle

If a2=b2+c2

Then triangle is a Right-angled triangle= Pythagoras theorem

If a2>b2+c2

Then triangle is an Obtuse angled triangle

5. (Here D is the midpoint of the AC side or AD = DC).

6. Length of the Median-

BD=122(AB2+BC2)−AC2

7. 3 (Sum of squares of sides) = 4 (Sum of squares of medians)

2. If two sides and one included angle is given-

Area = ½ x Product of given sides x Sin(given included angle)

Area=12×a×b×sin⁡C

{ex: sides a, b are given and included angle C is given}

3. If a side and its respective Altitude (perpendicular drawn on a side from the opposite vertex) is given, then-

Area of the triangle = ½ x Base x Height (Altitude)

Algebra

The Algebra section is a critical part of the Quantitative Aptitude section in the CAT exam. Below are over 50 important formulas for CAT preparation in this section, which are provided in this comprehensive CAT Formula Sheet:

1. Quadratic Equations

1. General Quadratic equation will be in the form of ??2+??+?=0

2. Values of ‘x’ which satisfies the equation are called roots of the equation. To find the roots the Shreedhara Acharya's Formula is used.

Roots of the equation,

x=−b±b2−4ac2a

Sum of the roots=−ba

Product of the roots=ca

Difference of the roots=Dawhere D=b2−4ac

If D>0, then the roots of the equation are real and distinct.

i. If D is perfect square, then roots will be rational; ex: x = 1,6

ii. If D is non-perfect square, then roots will be irrational or conjugate surds

ex: x=3−5,3+5

If D=0, then the roots of the equation are real and equal.

If D<0, then the roots of the equation are imaginary and distinct.

y=ax2+bx+cwhere a>0

• For y=ax2+bx+c, if a>0, the minimum value occurs at x=−b2a and is given by:
  y=−D4a(Minimum value)

• For y=ax2+bx+c, if a<0, the maximum value occurs at x=−b2a and is given by:
  y=−D4a(Maximum value)

Where D=b2−4ac is the discriminant.

If the roots of the quadratic equation are a and b, then the quadratic equation is:

x2−Sx+P=0where S=a+b and P=ab

That is:

x2−(a+b)x+ab=0

Progression & Series

In this chapter there are three types of progression, which are-

1. Arithmetic Progression

2. Geometric Progression

3. Harmonic Progression

Arithmetic Progression (A.P.)

If a is the first term and d is the common difference then the Arithmetic Progression (A.P.). can be written as-

• a, a+d, a+2d, a+3d, …

Where:

a = first term

d = common difference

Nth term of the A.P. –

Tn=a+(n−1).d

Here n is the no. of terms

Sum of the n terms of the A.P. (Sn) = Average of all the terms x no. of terms(n)

Average of the terms can be found out easily

• If no. of terms is odd then the middle term will be the average

Ex: 2,5,8,11,14 are the terms of the A.P. then middle term 8 is the average

So, the sum = avg. x n = 8 x 5 = 40

• If no. of terms is even then the average of middle terms will be the average of the A.P.

Sn=n2[2a+(n−1)d]

Shortcut Formulae

Sn=n2(a+l)(where a=first term, l=last term, n=number of terms)

n=l−ad+1(number of terms in A.P.)

Geometric Progression (G.P.)

If a is the first term and r is the common ratio then the Geometric Progression (G.P.) can be written as-

a,a.r,a.r2,a.r3,…

Nth term of the G.P. –

Tn=a.rn−1 where n is the no. of terms

Sum

• S∞=a1−rif |r|<1

• If r<1:
  Sn=a⋅1−rn1−r

• If r>1:
  Sn=a⋅rn−1r−1

Where:

a = first term

r = common ratio

n = number of terms

Sum of infinite terms of the G.P.-

S∞=a1−rif |r|<1

Where:

• a = first term

• r = common ratio

• |r|<1 ensures the series converges.

Shortcut Formulas

If there are odd no. of terms in a G.P., then the product of all terms are equal to the nth power of the middle term.

e.g. 2,6,18,54,162 are the terms of a G.P.

Then the products of all the terms = 185

Harmonic Progression (H.P.)

If a,b,c are in A.P., then 1a,1b,1c are in Harmonic Progression (H.P.).

n-th term of the H.P.=1n-th term of the corresponding A.P.

Series

Sum of first n natural numbers:
1+2+3+⋯+n=n(n+1)2

Sum of squares of first n natural numbers:
12+22+32+⋯+n2=n(n+1)(2n+1)6

Sum of cubes of first n natural numbers:
13+23+33+⋯+n3=(n(n+1)2)2

Sum of first n natural odd numbers:
1+3+5+⋯+(2n−1)=n2

Sum of squares of first n even numbers:
22+42+62+⋯+(2n)2=2n(n+1)(2n+1)3

Sum of squares of first n odd numbers:
12+32+52+⋯+(2n−1)2=n(2n+1)(2n−1)3

Indices & Surds

Product Rule:

am⋅an=am+n

Quotient Rule:

aman=am−n

Power of a Power:

(am)n=amn

Power of a Product:

(ab)n=an⋅bn

Power of a Quotient:

(ab)n=anbn

Negative Exponent:

a−n=1an

Shortcut Formulae

∏n=1∞a=limn→∞an

Logarithmic Rules and Properties

Definition of Logarithm:

logb⁡a=x⟺bx=a

Log of 1:

logb⁡1=0(for any base b>0, b≠1)

Log of the base itself:

logb⁡b=1

Log of a product:

logb⁡(mn)=logb⁡m+logb⁡n

Log of a quotient:

logb⁡(mn)=logb⁡m−logb⁡n

Log of a power:

logb⁡(mn)=n⋅logb⁡m

Change of base formula:

logb⁡a=logk⁡alogk⁡b(commonly with base 10 or e)

Base switch rule:

loga⁡b=1logb⁡a
